METHOD AND SYSTEM FOR SUPPORTING MULTIPLE PERIPHERAL COMPONENT INTERCONNECT PCI BUSES BY A SINGLE PCI BRIDGE WITHIN A COMPUTER SYSTEM

摘要

The present invention includes a plurality of peripheral connections in a data processing system: a method and apparatus that supports a number of peripheral devices via a local bus to a single PCI host bridge (host bridge) having a (Peripheral Component Interconnect PCI) interface. In the method and system according to the invention the processor and system memory are connected to the system bus. 2 the first and the PCI local bus is coupled to the system bus through a PCI host bridge. A first and a 2 PCI local bus is provided with a multiple-line electronic switch sets (sets of in-line electronic switch), PCI local bus is a PCI local bus segments to support the plurality of PCI peripheral slot by the in-line electronic switch It is divided into. Multiple in-line electronic switch set is a system bus via a single PCI host bridge in accordance with the opening and closing of the bus control logic circuit is opened or closed by the (bus control logic), up to 14 PCI peripheral slot is the inline electron switch set in the PCI host bridge and access.
